Self Lubricating Guide Pin | Automobile Die Guide Pin

The guide pin is mainly used on the continuous die to precisely position the strip to ensure the shape of the part and the position and size of the inner hole. The guide pin is installed on the blanking punch. Before blanking, the lead nail first enters the punched hole, aligns the relative position of the hole and the shape, and then blanks the material, so that the error of the feeding step can be eliminated, and the accurate positioning can be achieved.

In machinery, guide pins are mainly used for assembly positioning, and can also be used as overload shear connections in connection and relaxation level safety devices. The types of pins are: cylindrical pins, tapered pins, hole pins, cotter pins and safety pins.

Guide pins are generally made of materials with high hardness such as high-speed steel, tungsten steel, and cemented carbide, which are used to guide the position of the workpiece to ensure accurate blanking of the workpiece. The appearance of the guide pin is similar to the tip of the red tassel gun. Guide pin is a common mold accessory with very high precision. 

In the continuous die stamping process, how to transfer the semi-finished products to each stamping engineering station at an equal distance for stamping is the most important issue for continuous die stamping. If only relying on the external feeder, there will be other factors, and it is impossible to achieve the precise equidistant feeding target. Therefore, other methods are needed to assist the feeding distance accuracy, which requires our guide pin.
